I actualy find the Indian Toddlers to be quite a bit smaller, although I use both. My Indians are more absorbent though, so it works out. I use Toddlers on my 28-30 pound 20-month old and we love them. The premiums are not absorbent enough anymore, we get some soggy wool happening so that's the main reason I use the Toddlers.
The CPFs have enough extra lenth that I fold them down in the front and it completely doubles over my son's wet zone - so I have 4x8x4, so 16 layers, doubled, so 32 total. Make sense? With the Indians I do not have enough extra to double it over in length but they are absorbent enough that they work for us anyway. Good luck!
